At finishing facilities, heifers and bulls are reared in free-range conditions at their own rhythm for over a year. They are sent for slaughtering at an age of 1.5–2 years. Finishing facilities may be either "cold sheds", where animals are reared in groups in sheds on a thick layer of absorbent litter, or "warm sheds", where part of the floor of the shed contains a grille, which allows urine and faeces to run down into the manure storage area, while the remainder of the shed floor is a solid sleeping area. All of the shed types are built in such a way that all of the animals have sufficient space to lie down simultaneously. The most important factors in ensuring successful finishing are sufficient space and successful, methodical feeding. Normal bulls can weigh up to 800 kilogrammes when they are sent to slaughter.
